Description
In this work, BaCeO${}_3$ were prepared by a solid-state reaction method. BaCeO${}_3$ were calcined at 1300 ${}^{\circ}$C for 10 h in air and sintered at various temperatures. Phase formation analysis by X-ray diffraction technique (XRD) revealed that the samples exhibited a perovskite structure. The microstructural analysis indicated that grain size of the ceramics increased with sintering temperature due to higher different at a higher temperature. The dielectric constant of the ceramics tended to increased with the sintering temperature increase. In addition, complex impedance analysis was applied to determine grain boundary and grain responses of the ceramics. The analysis suggested that the electrical properties of BaCeO${}_3$ depended on characteristics of grain and grain boundary.
